My recommendation would be to do an overnight in charming Valladolid, and do one ruin each morning and a cenote in the afternoon. As a one day, doing both ruins would be a very long, hot, and exhausting undertaking with visual and historical overload likely.
It's a long weekend on a cheap fare to get some warmth. Using a BOGO certificate at the Intercontinental Cancun and so no change to move around hotels. Looks like you could do a really nice tour roaming the Yucatan peninsula, but not on this trip. I've got a one day out and back from Cancun only.
